How deadly dragonfly wings bust up bacteria

Scientists have revealed the intricate detail of how dragonfly wings kill bacteria, thanks to new methods for using very powerful microscopes to see nature's smallest structures in three dimensions.

A 100-fold leap to GigaDalton DNA nanotech

DNA, present in almost every cell, is increasingly being used as a building material to construct tiny, but sophisticated structures such as autonomous 'DNA walkers' that can move along a microparticle surface, fluorescent ...

Spin current from heat—new material increases efficiency

Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents." ...

Better, bolder printing with silicon nanostructures

From textbooks to artwork to newspapers, printed items are a part of our everyday life. But the ink used in today's printers are limited in colors and resolution. Now in a new study in ACS' journal Nano Letters, scientists ...
